Sidebar icons gone with Widgets

I have Nick La’s GlossyBlue theme installed, and just today activated a flickr widget, and then activated all of the other i wanted, such as: categories, archives, and blogroll. The problem is, that once i activated all of these, my fonts stayed the same and all, but the icons next to the list items disappeared. I have checked the CSS and the Page Source, yet i don’t see any reason why they should not still show. Has anyone had this problem before?
